How do you calculate transfer function?

To find the transfer function, first take the Laplace Transform of the differential equation (with zero initial conditions). Recall that differentiation in the time domain is equivalent to multiplication by "s" in the Laplace domain. The transfer function is then the ratio of output to input and is often called H(s).

What is a transfer function example?

For example, the transfer function of a two-port electronic circuit like an amplifier might be a two-dimensional graph of the scalar voltage at the output as a function of the scalar voltage applied to the input; the transfer function of an electromechanical actuator might be the mechanical displacement of the movable ...

What is the transfer function explain?

For finite dimensional systems the transfer function is simply a rational function of a complex variable. The transfer function can be obtained by inspection or by by simple algebraic manipulations of the differential equations that describe the systems.

How do you find the phase of a transfer function?

The phase part is just tan^-1(imaginary part)/(real part). As gneill pointed out, your transfer function phase angle will be the negative of the numerator phase angle, i.e. ψ = - tan^-1(imaginary part)/(real part) of the denominator.
